The Study was carried out on Pigeonpea (Cajanus cajan) with drip cum fertigation in transplanted Pigeonpeain Vertisols (Black-cotton soils) at Agricultural Research Station, Tandur, Vikarabad District, Telangana state, India. The experiment was conducted in Split-plot design with three replications comprised of Irrigation levels (four I1: , I2: : I3: and I4: IW/CPE ratio as main plots based on Pan Evaporation and Fertility levels three (F1: 75 % RDF, F2: 100 % RDF and F3: 125% RDF) as sub-plots. | Effect of nutrient management and micro-irrigation techniques on kharif pigeonpea Cajanus cajan.
